You can configure Firefox to use Kerberos for Single Sign-on. In order for this functionality to work correctly, you need to configure your web browser to send your Kerberos credentials to the appropriate KDC.The following section describes the configuration changes and other requirements to achieve this.

1. In the address bar of Firefox, type `about:config` to display the list of current configuration options.

2. In the Filter field, type `negotiate` to restrict the list of options.

3. Double-click the network.negotiate-auth.trusted-uris entry to display the Enter string value dialog box.

4. Enter the name of the domain against which you want to authenticate, for example, `.example.com`.

5. Repeat the above procedure for the network.negotiate-auth.delegation-uris entry, using the same domain.
